Didu didn’t know how many pages of the demand list were faxed to Zhou Qingfeng. It was really unusual for the person who wrote this list.

At first glance, it seems that many models and names of tools and devices are listed, but the list is also very skillful, which fully tests Zhou Qingfeng's supply capabilities.

For example, machine tool tools, high-speed steel is relatively ordinary, while cemented carbide is of high quality. Cubic boron nitride tools are very expensive and are not easy to buy.

As for ceramic tools, they are at the forefront of today's exploration of materials science.

The electronic devices behind are more particular, each one is higher-end.

High-power thyristors are widely used in the industrial field, and so in the military field. If Zhou Qingfeng can get it, it means he has some strength.

However, the Mos devices of gallium arsenide and gallium nitride tend to be military.

For example, the radar of a fighter needs to launch as much power as possible in the smallest space as possible, and satellites pursue extreme performance under extreme weight, which all require these things.

The domestic field is still in its infancy in these two fields, while the United States has begun to be practical.

The famous Aegis air defense system uses gallium arsenide devices in its radar. Its later improved models use gallium nitride.

Gallium nitride is still in a laboratory state, and its power density is one order of magnitude higher than gallium arsenide.

As for industrial control and high-speed A/D conversion chips, these are the core components of guidance weapons and are also extremely widely used in the industrial field.

Unlike civil-grade chips that work at room temperature, military chips must withstand severe temperature changes and vibrations, and must also work normally under strong electromagnetic interference.

If it is an aerospace chip, the computing performance does not need to be very strong, but in addition to the stricter environmental adaptation requirements than military chips, it must also be able to withstand the strong radiation of cosmic rays.

This makes this type of chip very difficult to deal with.

For example, the Atmel company, the At697f processor dedicated to satellites, is a product that will be exported to the outside world more than 20 years later. But the price of a chip is as high as 70 million US dollars.

In addition, there are those that are not exported to the outside world, and even the models are kept confidential.

The output of cutting-edge military chips is very low, with only hundreds or thousands of masks at a time. Each time there are special military personnel to guard them.

After production, all mask materials, chips and even scraps will be taken away. What I am afraid of is that someone secretly sells them.

If Zhou Qingfeng can really get high-end things, he will be very important in the hearts of the Didu ministries.

Open the window of the e-commerce plane, industrial garbage columns, machine tools and tools.

Different types of tools have their own applicable environments and cannot be replaced by each other. However, when it comes to high-tech directions, cemented carbide tools with cubic boron nitride coating are the first choice.

Boron nitride has a hardness second only to diamond, but its thermal stability is far superior to diamond, and its cutting performance is extremely excellent. It is a tool that can be used to process high-performance steel.

Research on cubic boron nitride began in the 1960s, but the basic industry was weak and the product stability was poor. This led to the stagnation of related research.

When the 1970s began, aircraft engines began to use iron-based high-temperature alloys, and ordinary tools could not process this thing at all. Only then did the country feel anxious about using cubic boron nitride.

By the 1980s, the situation was even worse. Automotive manufacturing, aerospace, and electronic technologies all required high-performance tools, and China could only find ways to import them.

A knife costs hundreds or thousands of dollars, so expensive it makes people cry.

By the 1990s, new materials and new technologies emerged one after another. Rabbits were forced to promote the progress of cubic boron nitride production technology through "external technical exchanges".

But even after thirty years, the domestic tool industry has not reached its peak and is still at the bottom of the industrial chain. The quality of finished tools is not high and they still rely on imports.

Zhou Qingfeng's fingers thrust, and two tons of used knives slammed on the handmade carpet in his luxury living room. The expensive Persian carpet was ravaged and was not decent.

The alchemy workshop was opened, and more than a dozen spiritual slaves floated out to be coolies, and moved scattered waste boron nitride knives into the alchemy array for repair.

This includes a large number of drill bit milling cutters, turning cutters, and planers, which are messy. It took half a day to carry it alone.

After getting the knives done, Zhou Qingfeng felt like he was going to make some cutting-edge things.

chip.

There is no foreign top-secret cutting-edge processor on the e-commerce plane. This thing is either launched into the sky or destroyed by supervision.

In fact, foreign military-grade chips are not common. They are either installed in missile shells for use on the battlefield or are destroyed after storage expires.

Most of the things that can be thrown away as garbage are industrial-grade.

For example, Zhou Qingfeng saw an ad585, a product from the American Adi company. This type of chip has different levels and its working environment is also different.

The S-level usage document indicates that the working temperature is 'negative fifty-five degrees to positive one hundred and twenty-five degrees', which is by no means an analog-to-digital conversion on the circuit board of sex toys.

Bought, bought, bought!

Zhou Qingfeng was about to take action, but he found that the minimum purchase volume was one ton. The ad585s was packaged using a fourteen-leg patch, and a chip weighed only a few grams.

It's enough to buy a ton, it's enough to bury him.

Buy something else.

Loongson 1e and Loongson 1f?

Hey..., these two chips are interesting!

This is a standard aerospace-level general-purpose processor, used for satellite-based computers. The Beidou series uses it. This kind of CPU is a bit too strong at present.

You should know that the computing speed of 486 is only 50 megabytes, and the Loongson 1e and 1f have reached 200 megabytes.

Strangely, domestic high-end chips are sold without restrictions on e-commerce planes, but foreign ones are not.

Speaking of the military-grade 486, we must talk about a story.

In 2001, Gao Zhan, a Chinese female scholar who received a US green card, and her family of three were preparing to return to the United States and were arrested by Guoan plainclothes at Didu International Airport.

You can make a spy movie for what happened next.

After Gao Zhan was arrested, her husband and son were soon released. After returning to the United States, the father and son actively lobbled for human rights organizations, media and members of Congress, demanding the "rescue" Gao Zhan.

The American media was uproar and collectively supported it.

This incident happened for several months. Gao Zhan's husband originally had a green card, but he was naturalized on the front line of the United States. The oath ceremony even went to the Capitol building.

A vote of senators and representatives delivered speeches, supporting Gao Zhan and demanding that the Rabbit government release her immediately.

On April 3 that year, the U.S. House of Representatives, the Judiciary Committee Immigration Group, and senior Democratic Rep. Sheila Jackson Lee proposed a bill (bill number:.1358).

The proposal proposes that Gao Zhan be exempted from taking oath to naturalize, so that the Eagle Sauce government can ask the Rabbit government for people in the name of Gao Zhan being a citizen of Eagle Sauce.

Do you think Eagle Sauce is shameless now? People have long been shameless.

But this is not the end!

On April 5, Virginia Republican Senator George Allen joined forces with six other senators from the Democratic Republican parties to file a similar bill in the Senate (bill number: s.702).

Both bills require the Attorney General of Eagle Sauce to immediately grant Gao Zhan Yingsauce citizenship without going through oath procedures. To put it bluntly, it is to mess up the situation.

By this time, things will be too big.

As early as March, Deputy Prime Minister Rabbit visited Hawkshop's house, and then President Bush and Secretary of State Powell raised objections to the matter.

But Gao Zhan is still a rabbit citizen, it’s nothing to do with your Eagle sauce.

What's the end of your business? What a pattern!

The next operation is dazzling.

On July 24, the Rabbit Procuratorate determined that Gao Zhan was engaged in espionage activities for Taiwan, and the court sentenced her to ten years in prison.

On July 25, a spokesperson for the State Council of Eagle Sauce said that he would use each level of diplomacy to put pressure on rabbits and encourage them to release their vision on human reasons.

On July 26, a spokesperson for the Hawkshop White House said that President Bush had a call with the third generation of the Rabbits for the first time since his inauguration, and discussed Gao Zhan**.

On the same day, Hawkshop Secretary of State Powell held a state visit at Didu, and put pressure on the rabbit on this issue.

Everyone thinks that rabbits will definitely not surrender. But what follows is the turn of the circle.

On the 26th, Gao Zhan, who had just been sentenced, was allowed to "release medical parole". She quickly fled to Ying Jiang's house and was welcomed like a hero. She also delivered a famous speech at the airport.

President Bush was proud of this, feeling that his own pressure had played a role. The Hawkshop media even cheered that this was a victory of 'freedom and democracy'.

But......

By 2003, Gao Zhan was arrested again for espionage. But this time the arrest was Ying Jiang FBI.

A Virginia court accused Gao Zhan of selling high-tech products that were prohibited from export to Rabbit's China Electric Power 14 since 1998.

This includes dozens of military-grade 486 chips.

Gao Zhan and her husband were imprisoned for this.

This incident was so vigorous but a slight start. Ying Jiang was so embarrassed that he was not mentioned later.

But the rabbit lost a "deep sea" and it was a big loss no matter how you look at it.

This can tell how important cutting-edge chips are.

But now, Zhou Qingfeng has more military-grade 486 chips, and even more advanced ones.

But......

No, no, it's only 91 years now.
